Question

Single letter symbol for arginine is:

• A. \( \text{K} \)
• B. \( \text{D} \)
• C. \( \text{R} \)
• D. \( \text{G} \)

Hint:

Amino acid single-letter codes simplify sequence notation and computational protein analysis.

Answer 1

The Correct Option is C

The single-letter code for arginine is R, derived from its basic and positively charged nature. Amino acids have standard single-letter symbols, helping in protein sequence representation. For example, glycine (G), lysine (K), and aspartic acid (D) follow similar conventions.
